Foldable Display Screen for Suitcase with Expandable Viewing Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The small display screen size of electronic devices, such as smartphones and laptops, fails to meet the needs of users who want to watch videos or share information during travel, as it provides an inadequate viewing experience.
Innovation Solution
A suitcase equipped with a foldable flexible display screen that includes a fixed first display unit and at least one second foldable display unit, which can be unfolded to increase the display area, along with additional features like a wireless module for internet connectivity, a positioning module for real-time location tracking, and a battery charging system using an electric generator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a small display screen is used in electronic devices, then the device size is reduced and portability is improved, but the display area is insufficient for watching videos or sharing information during travel
Solution Approach 1:
The display screen is divided into multiple independent display units that can be folded or unfolded relative to each other. This segmentation allows the display area to be expanded when needed while maintaining a compact form when folded, resolving the contradiction between large display area and compact structure.
Solution Approach 2:
The display screen employs a foldable structure with movable connections between display units, transitioning from a static small screen to a dynamic expandable display. This dynamic capability allows the display area to adapt between compact and expanded states, solving the contradiction between portability and display size.
2Area of moving object
If a foldable display screen with multiple display units is implemented, then the display area is increased, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
By dividing the display into separate modular units with standardized connection interfaces, the manufacturing process can be simplified through modular assembly. Each display unit can be manufactured independently and then assembled with standardized mechanisms, reducing overall manufacturing complexity despite the increased display area.
Solution Approach 2:
The foldable display units are designed to nest within each other when folded, similar to nested dolls. This nesting arrangement maximizes space efficiency and simplifies the structural design, making the complex multi-unit display easier to manufacture and assemble while maintaining a compact folded state.

AI summary
A suitcase includes a case body. The case body is provided with rolling wheels and a pull rod. A foldable display screen is provided on an outer surface of the case body. The display screen includes a fixed first display unit and at least one second display unit which is foldable relative to the first display unit. When the display screen is in the folded state, the at least one second display unit is folded on and overlapped with the first display unit. After the at least one second display unit is unfolded relative to the first display unit, the display screen is in the unfolded state, and the display area of the display screen is equal to the sum of the first display unit and the at least one second display unit.
